Remote NFSv4 Client

$ ls /mnt/storage/aaaaaaa_aaa/bbbb/cccc_ccccc gives this error:
ls: reading directory .: Too many levels of symbolic links

How can I fix this?

When error occurs ls start listing the files, however PHP brakes.

On the NFSv4 Server

In /etc/fstab:

/mnt/storage    /srv/storage    none    bind    0 0

In /etc/exports

/srv         192.168.1.0/24(rw,async,insecure,no_subtree_check,crossmnt,fsid=0,no_root_squash)
/srv/storage   192.168.1.0/24(rw,async,nohide,insecure,no_subtree_check,no_root_squash)

ERROR

-rw-r--r-- 1 root root  12968 Mar 30 11:05 1000008.gz

I came across it in PHP. scandir would return 1612577.gz & 1612579.gz, but skips 1612578.gz and yet the file types and properties are identical on them

and this only happens on the nfs client, works 100% on the server

What's ls -l /mnt/storage/aaaaaaa_aaa/bbbb/? –  Jay Jul 6 '12 at 22:51
    
Works fine. There are few folders there. cccc_ccccc has many files under it. Also same command works on the NFS server itself fine. –  user1434058 Jul 6 '12 at 22:57
    
What's the output? cccc_ccccc is probably a relative symlink that is causing a loop. –  Jay Jul 6 '12 at 23:16
    
800k sequentially numbered files, example: -rw-r--r-- 1 root root 13459 Mar 30 06:26 9061.gz –  user1434058 Jul 6 '12 at 23:29
    
Ah, then how about file /mnt/storage/aaaaaaa_aaa/cccc_ccccc? –  Jay Jul 6 '12 at 23:38

1 Answer 1

Somewhere you have a symbolic link that points back to its parent. Use this to find it:

find /mnt/storage -type l -exec ls -l {} \;

Once you do, then perhaps you can figure out how to correct it.
